Evaluating the evidence base for relational frame theory: a citation analysis

Relational frame theory (RFT) is a contemporary behavior-analytic account of language and cognition. Since it was first outlined in 1985, RFT has generated considerable controversy and debate, and several claims have been made concerning its evidence base. The present study sought to evaluate the evidence base for RFT by undertaking a citation analysis and by categorizing all articles that cited RFT-related search terms. A total of 174 articles were identified between 1991 and 2008, 62 (36%) of which were empirical and 112 (64%) were nonempirical articles. Further analyses revealed that 42 (68%) of the empirical articles were classified as empirical RFT and 20 (32%) as empirical other, whereas 27 (24%) of the nonempirical articles were assigned to the nonempirical reviews category and 85 (76%) to the nonempirical conceptual category. In addition, the present findings show that the majority of empirical research on RFT has been conducted with typically developing adult populations, on the relational frame of sameness, and has tended to be published in either The Psychological Record or the Journal of the Experimental Analysis of Behavior. Overall, RFT has made a substantial contribution to the literature in a relatively short period of time.     

Let's find the evidence: an analogue study of confirmation bias in criminal investigations

People involved in criminal proceedings (e.g. police officers, district attorneys, judges, and jury members) may run the risk of developing confirmation bias, or tunnel vision. That is, these parties may readily become convinced that the suspect is guilty, and may then no longer be open to alternative scenarios in which the suspect is actually innocent. This may be reflected in a preference for guilt‐confirming investigation endeavours, as opposed to investigations that are aimed at confirming, or even excluding, alternative scenarios. In three studies, participants read a case file, and were subsequently instructed to select additional police investigations. Some of these additional endeavours were guilt‐confirming (i.e. incriminating), whereas others were disconfirming (i.e. exonerating). Results suggest that additional investigation search was guided by an initial assessment of the suspect's guilt (Study 1). Furthermore, participants' tendency to select incriminating investigations increased with increased crime severity, and with the strength of the evidence present in the case file. Finally, the selection of incriminating investigations was associated with conviction rates (Study 3). However, in general, participants did not favour incriminating endeavours. That is, in the three studies, the percentages of selected incriminating endeavours did hardly or not exceed 50%. Copyright © 2010 John Wiley & Sons, Ltd.     

Children's appraisals of sex-typed behavior in their peers

Four experiments evaluated the effect of variations in sex-typed behavior in hypothetical peers on children's ratings of friendship. In all four studies, the children were heterogeneous with regard to social class, ethnicity, and race. In Experiment 1, children (71 boys, 90 girls) in Grades 3–6 read five stories about a target boy and in Experiment 2 (102 boys, 137 girls) about a target girl who displayed four sex-typed behaviors that ranged from exclusively masculine to exclusively feminine. In Experiment 1, boys preferred the exclusively masculine boy most as a friend. With each addition of a feminine behavior (and corresponding subtraction of a masculine behavior), the friendship ratings became increasingly negative. In contrast, the girls preferred the exclusively feminine boy most as a friend and, with each addition of a masculine behavior, the friendship ratings became increasingly negative. In Experiment 2, the converse was found although girls' ratings of friendship were less sharply affected by the target girl's sex-typed behavior than was observed for boys' ratings in Experiment 1. In Experiment 3, children (33 boys, 38 girls) in Grades K—2 were read three stories about a target boy, accompanied by detailed chromatic illustrations, whose four sex-typed behaviors were exclusively masculine, equally masculine and feminine, or exclusively feminine. The boys had significantly more favorable friendship ratings than the girls; however, in contrast to Experiments 1 and 2, the target boy's sex-typed behavior did not affect friendship ratings of either boys or girls. Experiment 4 (28 boys, 27 girls) repeated the procedure of Experiment 3 with children in kindergarten and Grade 1; in addition, the children made forced-choice friendship ratings for each of the three possible story pairs. In contrast to Experiment 3, boys' friendship ratings were affected by the target boy's sex-typed behavior, as observed in Experiment 1, but girls' friendship ratings were not. However, in the forced-choice situation, the boys significantly preferred the exclusively masculine boy whereas the girls significantly preferred the exclusively feminine boy. The results were discussed in relation to the influence sex-typed behavior has on modifying the effects of a peer's sex on affiliative preference and sex differences in appraisals of cross-gender behavior, including the concept of threshold effects.     

Validation of the Life Role Salience Scale in a South African setting

This study aimed to validate the Life Role Salience Scale (LRSS) in a South African context. Respondents were 300 working adults (72.3% = women; 57.9% = non-white; mean age = 35.12 years, SD = 10.25 years; mostly from the finance sector = 35.6%). Confirmatory factor and exploratory factor analyses were conducted to determine the LRSS’s factor structure and reliability of scores from the scale for the South African sample. Results yielded five factors emerging from the analyses: Homecare role reward value and homecare role commitment; marital role reward value and marital role commitment; occupational role commitment; occupational role value reward; and parental role reward value. The reliability of scores from the LRSS ranged from 0.79 (parental role reward value) to 0.95 (homecare role reward value and homecare role commitment). The LRSS shows validity for research use in South Africa.     

EMS Perspectives on Coping with Child Death in an Out-of-Hospital Setting

To understand the ways that EMS providers cope with pediatric death in an out-of-hospital setting, eight focus groups were conducted with 98 urban, rural, and suburban EMS providers. Sixty-eight of the participants also completed a short questionnaire about a specific event. In both the focus groups and questionnaire, participants were asked how they individually coped with the death, how they coped as a team, and what coping strategies were most and least helpful. Specific coping strategies were found to be helpful to EMS providers, and could be classified as Solve, Solace, Dismiss, and Escape based on whether they approached or avoided the problem or the emotion.
